Modelling flotation froths Modelling flotation froths Neethling, S.J.; Cilliers, J.J. 2003 09 29 000000 This paper gives a brief description of a fundamentally based model for the behaviour of a flotation froth. It includes descriptions for all three phases present in a flotation froth.
26 The Open Mineral Processing Journal, 2011, Volume 4 Khoshdast and Sam importance of frothers in flotation is widely acknowledged, particularly in terms of their role with respect to bubble size, and the stability and mobility of the froth phase.

Global Froth Flotation Chemicals Market Geographical Analysis Asia Pacific was estimated to be the leading regional market and presence of a large number of manufacturers and vendors of froth flotation chemicals is the critical factor which is responsible for the growth of the region.
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
The Froth Flotation Machine is so designed that it will do a most acceptable job for coarse as well as fine flotation. The selectivity and flexibility are outstanding features and these, coupled with low operating and maintenance costs, makes the Sub A synonymous with the word FLOTATION.

Froth flotation is one of the most broadly used separation methods in the mineral processing industry. However, despite being introduced in the early 1900s and numerous years of research and development, flotation is still not fully understood and remains relatively inefficient.
FROTH FLOTATION RECENT TRENDS @IIME, JAMSHEDPUR, 1998; pp. 18 41 Flotation of Sulphide Ores HZL Experience V.P. KOHAD Hindustan Zinc , Zawar Mines, Udaipur 313 901 ABSTRACT Flotation process, patented in the year 1906, was originally developed for mineral industry to recover values from high grade tailings of gravity separation plants.
The importance of froth flotation process is that, it is easy to separate two sulphide ores present in a mixture (by adjusting the oil water proportion or by using depressants). Also this process is significant because it allows for the economic extraction of metals from lower grade ores.

As the flotation process of today is essentially that of making a mineral buoying froth in modified water, it is not necessary for me to make further reference to the patents granted for
Froth flotation definition is flotation in which air bubbles are introduced into a mixture of finely divided ore or other material with water and a chemical that aids attachment of the bubbles to the particles of the desired material and its recovery as a froth.
